JAR-CLOSURE TOOL.

To all whom it may concern.-

Be it known that I, FRANK R. N ICE, a citi- Zen of the United States,residing at Lansing, in the county of Ingham and State of Michigan, haveinvented new and useful Improvements in J ar-Closure Tools, of which thefollowing is a specification.

This invention relates to improvements in devices for securing closuresto the top of jars. l

The object of the invention is to provide a tool comprising a plate forengaging the threads of a jar-closure, a lever swiveled to the plate andprovided with flanges to engage therewith to turn it, and acrimping-roller to crimp the lower edge of the closure into or down onthe sealing-gasket.

The invention also comprehends improvements in the specific details ofconstruction,

as will be hereinafter described, and particularly pointed out in theclaims.

In the drawings, Figure 1 is a perspective view of the invention; Fig. 2is aside elevation illustrating the first step in the operation of myinvention. Fig. 3 is a similar view showing the next step in theoperation of the invention. Fig. 1 is a central vertical section. Fig. 5is a transverse section on the line :0 m, Fig. 4:. Fig. 6 is a view of amodification.

The same numerals refer to like parts in all the figures.

1 indicates a plate having downwardly-extending flanges 2 at oppositesides, each flange provided with an inwardlyextending rib 3 to engagethe threads of a closure 4. The plate 1 has straight side walls on oneside the center, and at the center is formed an opening 6.

7 indicates an operating-lever having perforated ears 8 at one end,through which passes a pin 9 to pivot a swiveled bearing-post 10,adapted to fit in the opening 6. On one surface of the lever 7 andadjacent the ears 8 are a pair of parallel flanges 11, spaced to fit thewalls 5 of the plate 1. Projecting from the lever in an oppositedirection from the flanges 11 is an arm 12, carrying a crimping-roller13, the handle 14. extending outwardly from the arm.

In operation the closure et of threaded type is screwed on the mouth ofthe jar 1 Then the plate 1 is screwed on the threads of the closure, andthe lever is turned on the post 9 and positioned to engage the flangesll 11 Specification of Letters Patent.

with the walls 5. The operator now turns the lever, and by theconnection with the plate the latter is screwed down hard on theclosure, which in turn screws said closure tight on. the jar. After theclosure is screwed down as tight as desired the lever is elevated todisengage the flanges 11 11 from the walls 5, and it is turned around onthe post 9 to bring thearm 12 down toward the jar-closure. This havingbeen done and the plate 1 still tightly holding the closure, pressure isapplied to the lever to cause the roller 13 to bear hard on theflange'QO, the lever is turned around several times, and the flange 20is crimped tightly into the gasket 21. The crimping action having beenaccomplished, the lever is again turned over to engage the flanges 11 11with the walls 5, and the movement is reversed to disengage the flanges2 from the closure.

My inventionis extremely simple and durable and is capable ofeffectually screwing a closure and crimping its edge to tightly engagethe gasket to prevent the admission of air to the jar.

In the modification shown in Fig. 6 I show the plate 1 hinged, as'at 22,to adapt the invention to closures of varying sizes. In other respectsthe details are the same as hereinbefore described.

What I claim as new is- 1. A tool of the character described comprisinga plate having means for engaging a jar-closure and provided withopposite edges with which alever engages, said lever being provided withopposite flanges to engage the opposite edges of the plate to turn itand a roller to crimp the closure, and a swiveled connection between thelever and the plate.

2. A tool of the character described, comprising a plate having meansfor engaging a jar-closure, a lever provided on one surface with meansto engage the plate and an arm bearing a roller projecting from theopposite surface of the lever to crimp the closure, and a swiveledconnection between the lever and plate to operatively position eitherthe means for engaging the plate or the projection carrying the roller.

3. A tool of the character described, comprising a plate having meansfor engaging a jar-closure andv provided with opposite edges with whicha detachable lever engages, said detachable lever being provided withopposite flanges which engage the opposite edges of the plate forturning the said plate and means on the lever for crimping the closureafter it has been screwed in place.

4. A tool of the character described, comprising a plate, a lever, apivot-post engaging an opening formed in the piate, a pivot connectingthe lever and the post, flanges extending from the lever to engage andturn the plate when lateral pressure is applied to the lever, and an armbearing a roller projecting from the lever to crimp a jar-closure, thelever 01' the flanges being brought into operative position by turningthe lever on the pivot-post.

5. A tool of the character described, comprising a plate provided Withdepending flanges With projections to engage the threads of ajar-closure, an operative surface formed on the plate, and a leverswiveled to the plate,

said lever having flanges to engage the operative surface of the plateand an arm bearing a roller to crimp the closure, the flanges or theroller being brought into operative posi- FRANK R. NICE.
